Bain Extentioniste is a hair strengthening shampoo and a hair strengthening treatment that boosts strong hair growth starting at the roots.

Bain Extentioniste is a shampoo to help hair grow not only in length but in strength thanks to added Creatine, an amino acid that reinforces the internal structure of the hair fiber.
